Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Storyline

When Miami dentist Ted Brooks learns that his birth mother has passed away and that he was named in her will, he travels to Alaska to claim his inheritance. Rather than the large chunk of change that many people would expect, Ted instead receives his mother's pack of rowdy sled dogs and her property. Although the dogs seemingly have it in for Ted, he decides to keep the dogs and race them in the local race, the Arctic Challenge, spiting a mountain man who wants the dogs. What follows is a comedy detailing Ted's adventures in learning to run the sled dogs.—Anna <dimenxia@yahoo.com>
Response: Ted Brooks, a Miama dentist, finds out his birth mother died and has to go to Alaska for his inheritance: a pack of sled dogs that seem to have it out for him. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.
